MixTape is a simple, beautiful, and easy-to-learn application for making beat-matched mixes. By simply dragging-and-dropping the music you already have in iTunes (or from the Finder), MixTape adds detected tempo and beats. Tracks are then dragged onto a workspace where they now "snap to grid" along their beats and play in sync. Precisely in sync. Emphasized markers show where musical phrases start and a simple envelope adds that all-important final polish to your mixes. MixTape Pro adds a "HiLo" control, dropping the bass or treble for cleaner mixes; a "live" UI where you can hear what is under the playhead at all times, and a spectrogram which visualizes beats and phrases with better clarity than traditional waveform displays.
Mixes can then be exported at a configurable bitrate back into iTunes to play on your Mac, iPod, or iPhone; or published directly onto the Web with no additional accounts, services, or software. MixTape Pro adds the ability to play your mixes live through a second audio interface - simply cue up your first track, start the live stream, then continue to use your headphone to mix as usual. The live stream will also transmit MIDI, so lighting or VJ rigs can be kept in sync with the music as it is played. Pro can use a 'night' color scheme to reduce glare when playing in dark environments.
Far simpler than either an audio workstation or a DJ app, MixTape embraces the Mac aesthetic to blend in perfectly with your desktop. Finally a short series of video tutorials emphasize 'show' over 'tell' and creative commons licensed demo mixes both show what can be done and how.
